使用循环HPV-DNA的液体活检显示出对监测HPV阳性口腔癌的前景. 可检测的水平与晚期疾病和复发相关,有助于治疗决策.
科学领域:
- 在瘤学瘤学.
- 病毒学 病毒学
- 分子诊断学 分子诊断
背景情况:
- 人类乳头瘤病毒 (HPV) 是口腔状细胞癌 (OPSCC) 的关键原因.
- 像p16INK4a这样的当前生物标志物对于全面的风险分层和监测是不够的.
- 对于低风险的OPSCC患者,正在考虑降低治疗升级,需要更好的预后工具.
研究的目的:
- 探索液体活检的实用性,特别是循环瘤HPV-DNA (ctHPV-DNA),作为HPV阳性OPSCC的诊断和预后生物标志物.
- 评估ctHPV-DNA与瘤阶段,转移和治疗结果的关联.
- 突出ctHPV-DNA在监测疾病进展和复发方面的潜力.
主要方法:
- 使用滴滴数字/定量PCR和下一代测序在血中检测HPV E6和E7瘤基因.
- 在诊断时和随访期间分析ctHPV-DNA水平.
- ctHPV-DNA检测和水平与临床参数和治疗反应的相关性.
主要成果:
- 诊断时检测到ctHPV-DNA与晚期瘤阶段和转移的存在有关.
- 在治疗期间检测到和增加ctHPV-DNA水平与治疗失败和疾病复发相关.
- 液体活检为检测病毒相关瘤提供了高特异性.
结论:
- 流通的HPV-DNA显示出作为HPV阳性OPSCC风险分层和监测的非侵入性生物标志物的巨大潜力.
- 诊断程序的标准化对于液体活检的临床实施至关重要.
- 未来的应用可能包括对HPV阳性OPSCC患者的实时疾病进展监测.
